一、启动

/usr/local/nginx/sbin/nginx
或者
cd /usr/local/nginx/sbin
./nginx

二、关闭

查询主进程号：

root@ubuntu:/usr/local/nginx/conf# ps -aux |grep nginx
root        0.0  0.0       ?        Ss   :   : runsv nginx
root        0.0  0.0       ?        S    :   : svlogd -tt /var/log/gitlab/nginx
root        0.0  0.2     ?        Ss   :   : nginx: master process /opt/gitlab/embedded/sbin/nginx -p /var/opt/gitlab/nginx
gitlab-+    0.0  0.3     ?        S    :   : nginx: worker process
gitlab-+    0.0  0.3     ?        S    :   : nginx: worker process
root     46240  0.0  0.0  22284   376 ?        Ss   16:12   0:00 nginx: master process /usr/local/nginx/sbin/nginx
nobody     0.0  0.2     ?        S    :   : nginx: worker process
root       0.0  0.2     pts/    R+   :   : grep --color=auto nginx

查出主进程号为  46240

------------------------------

顺序停止   kill -QUIT 主进程号

　快速停止   kill -TERM 主进程号

　强制停止   kill -9 nginx

-------------------------------

若nginx.conf配置了pid文件路径

aaarticlea/png;base64,iVBORw0KGgoAAAANSUhEUgAAANAAAAAoCAIAAAAAB+NXAAABG0lEQVR4nO3VUQ6DIAwAUO5/afa3mIkVVBCW9+LHJFhL27iUAAAAAAAAAACAp+WU8ts5zOhbl5oCHe3JC9Y390z7TthhlXynm00DVxNnLRMO3Ay65J9L181oy+mR9qKl2Br3hTsawaOhfGpe3xKfqLhYrMl+c3FPHPP0FUGngtPd7+ZjzS3+nx79jm//Y+CKJ2qqUtDF05hBSvWPBwd8v5sG7vLAfW/jcWmNWZnS0dv3JupmLl1zpdjf/e7GJboQ828HbhvXF25/G3yEOu28kNLpCM7VzTjvYPF0fX41JypuLj6+XYzf8lPzuJj1V9pFO82zdb2XteZmgMrSN9VtWDsfCd4xwxW/VQP0KMuAUusmAAAAAAAAAABDfQBzYugmPX1QOwAAAABJRU5ErkJggg==" alt="" />

如果没有，则在logs目录下

　　kill -信号类型 '/usr/local/nginx/logs/nginx.pid'

三、重启

检查配置文件是否配置正确：

nginx -t -c /usr/local/nginx/conf/nginx.conf

或

/usr/local/nginx/sbin/nginx -t

更改配置后重启nginx

kill -HUP 主进程号或进程号文件路径   #可以不停止进程的情况下重新读取配置文件
或者使用
cd /usr/local/nginx/sbin
./nginx -s reload

四、升级

　　1、先用新程序替换旧程序文件

　　2、kill -USR2 旧版程序的主进程号或者进程文件名

　　　　此时旧的nginx主进程会把自己的进程文件改名为.oldbin，然后执行新版nginx，此时新旧版本同时运行

　　3、kill -WINCH 旧版本主进程号

　　4、不重载配置启动新/旧工作进程

　　　　kill -HUP 旧/新版本主进程号

　　　　从容关闭旧/新进程

　　　　kill -QUIT 旧/新进程号

　　　　快速关闭旧/新进程

　　　　kill -TERM 旧/新进程号

群网友交流的方法

重启：

/usr/local/nginx/sbin/nginx -s reload

停止：

/usr/local/nginx/sbin/nginx -s  stop

测试配置文件是否正常

/usr/local/nginx/sbin/nginx -t

强制关闭

pkill  nginx
